Query Vertica

To query Vertica with Flux:

  1. Import the sql package.

  2. Use sql.from() and provide the following parameters:

    • driverName: vertica or vertigo
    • dataSourceName: See data source name
    • query: PSQL query to execute
import "sql"

sql.from(
    driverName: "vertica",
    dataSourceName: "vertica://username:password@localhost:5433/dbname",
    query: "SELECT * FROM public.example_table",
)

Vertica data source name

The vertica and vertigo drivers use the following DSN syntax (also known as a connection string):

vertica://<user>:<password>@<host>:<port>/<database>?<queryArgs>

The vertica and vertigo drivers use the vertica/vertica-sql-go implementation. For information about supported DSN query arguments, see the vertica/vertica-sql-go documentation.

Vertica to Flux data type conversion

sql.from() converts Vertica data types to Flux data types.

Vertica data type Flux data type
INT, INTEGER, BIGINT, SMALLINT, TINYINT, INT2, INT4, INT8, SERIAL2, SERIAL4, SERIAL8 int
FLOAT, FLOAT4, FLOAT8 float
DATE, TIME, TIMESTAMP time
BOOL bool
TEXT, VARCHAR, VARBINARY string

All other Vertica data types are converted to strings.

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
